FOLDING B0X.

senorricnrrori forming part of 'Letters Patent No. 742,159, dated october 27, 1903. Application filed January 23,1903. Serial No. 140,220. (No model To it-ZZ whom, it may concern:

Be it known that I, WILLIAM E. BURTON, a citizen of the United States, and a resident of the city of New York,borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Folding Box, of which the following is a full, clear, and exact description.

The invention relates to folding-boxes,such as shown and described in the Letters Patent of the United States No. 716,665, granted to me December 23, 1902.

The object of the present invention is to providev a new and improved folding box formed of a single blank and arranged to economize in the use of the material, to allow convenient and quick setting up of the box from the dat blank, and to securely lock the integral parts in the set-up position.

The invention consists of novel features and parts and combinations of the same, as

, will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate cor-` responding parts in all the views.

Figure l is a face View of the blank for forming the box-body or the box-cover. Fig. 2 is a perspective View of the improvement partly set up. Fig. 3 is a similar view of the same, showing one end complete and 'the other end unlocked. Fig. 4 is a longitudinal sectional elevation of the improvement on the line 4 4 of Fig. 5. Fig. 5 isa transverse section of thesame on the line 5 5 of Fig. 4; and Fig. 6 is a like view of the looking device of the improvement, the section being on the line 6 6 of Fig. 4. v Y

The blank from which the box-body or the box-coveris formed is made from a single piece 'of paper or other material and consists, essentially, of a middle portion A, from the sides of which extend integrally the sides B1 and B', each terminating at its ends in flaps C C', and the said middle portion A terminates at each end in an integral outer covering-flap D, provided at its free end with a locking-tongue'E and connected at its sides by iianges F F with the end iapsC C on the corresponding end ofthe box.

rIhe end ilap C at each end of the box isI provided with a slot O2, extending in the direction` of the length of the iiap a short 4distance from the outer side thereof, as plainly illustrated in the drawings, and this slot C2 is adapted to receive the corresponding locking-tongue E, which latter has its shank E' approximately of a width corresponding to the length of the slot C2, and the head E2 of the locking-tongue h assidewiseprojecting teeth E2 for abutting against the outer face up, and the headE2 is passed through the slot C2. (See Figs. 4, 5, and 6.)

The vhead E2 of each locking-tongue has ta pering sides and is preferably provided with vof the end flap C at the time the box is set a transverse crease E4 at the' junction of the shank with the head and with a transverse crease E5 midway of the head E2, so as to facilitate forcing the head E2 through the slot C2 when setting up the box to bring the head E2 to the outer face of the end flap C.

Each end flap C is preferably of a length corresponding to the Width of the box and is of a width correspondingto the h eight of the box, so that when the box is set up each end iiap C not only forms a locking-Hap, but also an inner covering-flap in contradistinction to the outer covering-flap D, previously inentioned. l

v'The anges F and F' at each end of the box are partly formed by the outer coveringiiap D and the end iiaps C C', as plainly shown in Fig. 1, and the flange F has a portion of its outer side separated from the corresponding portion of the inner side of the end fiap C by forming a slot G between the said sides, so that the end locking-Hap C can be folded transversely to form the inner end flap, and at the same ,time'the flange F doubles up on the inner face of the outer liap D, the same as the iiange F', to give the box a fine appearance, as indicated in Fig. 3-that is to say, the tapering sides of the outer flap D continue in the iianges F and F' doubled up on the i'nside of the said outer covering-flap.

The several parts above mentioned are separated from each other by suitable creases or scores H, (mainly shown in Fig. 1,) so that the blank can be readily converted into a box body or cover by first turning the sides B and B' up at right angles to the middle portion A,

ICO

then turning the end locking-flap C inward to stand at right angles to the turned-up sides B and B, after which the other end flap C is swung transversely onto the outer face of the flap C, so that the anges F and F are doubled up on the outer lap D, swung up against portions of the flaps C and C', and then the locking-tongue E is swung inward and downward, and its head E2 is forced through the slot C2 of the inner end locking-Hap C, so that the several parts are securely fastened together.

In order to"bring the top of the end locking-tongue E flush with the top of the boxbody when set up, I provide each of the lockingilaps C with a recess C3 and the end fiap C' with a recess C4 arranged in such a manner that when the box is set up the recesses C3 and (l4 at each end of the box are in register for the reception of the corresponding shank E of a lockingtongue E.` The recess C3 is of a length corresponding to the width of the shank E', so that the latter holds the flap C against transverse movement, and hence the end parts of the box are not liable to open accidentally.

By having the teeth E3 projecting beyond the ends of the slot C2 on the outside of the viiap O it is evident that the head cannot acci- A box body or cover made from a single blank, as described, permits of shipping the blank in a iiat state, so as to take up comparatively little room, and the blank can be easily converted into a box body or cover for securely holding the material with which the box is to be filled.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A paper box made from a single piece and comprising a middle portion, sides integral with the sides of the middle portion, end aps integral with the ends of the said sides, outer covering-flaps integral with the ends of the middle portion and provided at their free ends with locking means, reversely-located anges at the ends of the box, integrallyconnecting the outer covering-flaps with the adjacent end iaps, for practically the full extent of each, and other reversely -located langes at the ends of the box, also connecting the outer coveringiiaps with the adjacent end iiaps for a part only of the extent of each.
